UWP Community Toolkit 1.4 is a smaller update as compared to the previous one, and focuses mainly on improving the numerous controls that were introduced before. Microsoft claims that the update brings better accessibility to controls, saying that every control can be used with a keyboard, a mouse, or via touch input. Additionally, controls now provide more information to the Narrator, improving compatibility with screen readers.

Microsoft has also begun a new project called "Microsoft.Toolkit.Uwp.DeveloperTools" and introduced a NuGet package as well. The company says that it aims to provide support tools to developers. As such, it has introduced two controls namely "FocusTracker" and "AlignmentGrid". The company notes that these tools are not intended to be deployed with your app, but are to be used during its development.

Other changes included in UWP Community Toolkit 1.4 are:

Carousel: A new control that presents items in a list, where the selected item is always in the center and other items are flowing ­around it. This reacts not only to the content but also to layout changes, so it can adapt to different form factors automatically. The carousel can be horizontal or vertical.

Search box for Sample App: The new Sample App allows you to search for a sample directly from the main menu.

The toolkit can be utilized in any app across PC, Windows 10 Mobile, Xbox One, HoloLens, and Surface Hub, provided that they are running the Windows 10 November Update - which is build 10586 - or above.
